Obtained from: gcc pre4.3 (GPLv2) branch
MFC after: 3 weeks
There is a bug in gcc (GCC/35998) where dwarf reports
sizes of unsigned -1 (0xffffffff).
On NetBSD this generated a faulty CTF entry which then
caused a segfault in ctfmerge. The issue was worked
around in NetBSD's Dtrace but since the issue originated
in gcc, it seems reasonable to fix it here.
Upstream gcc has been slow to react to this issue and
the author that submitted the patch is not interested
in licensing the change to us, so I did an independent
workaround for the issue.
MFC after: 1 week
of just blowing up. A very similar change to this exists which is
GPLv3 licensed, this is my own change.
This problem was triggered by running the Boost regression tests.
